摘　　要：简要阐述了220 kV MOA测量直流1 mA时的直流参考电压U1mA和75%U1mA直流电压下的泄漏电流试验的拆引线与不拆引线两种试验方法接线,并进行了实测结果比较和误差分析。最终结果表明,不拆高压引线的测量效果良好、方法可行。The measurement of DC reference voltage U1mA of 220 kV MOA under dc lmA and leakage current test of 220 kV MoA under dc 75% UlmA through two-test methods of lead and without lead demolished are introduced briefly, and the measurement results comparison and error analysis are carried out. The final result shows that the measurement result without high voltage lead demolished is good and feasible.
